' APPARATUS FOR MIXING COLORS.

Application filed March 6, 1914. Serial No. 822,909.

- Be-it known that I, OTTO Scnrrrz, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Apparatus for MixingColors, of which the'following is a specification.

This invention relates to apparatus for thoroughlym ixinga colorsolution for the purpjo'se'of infusingwith paper pulp andpreventing-mottled effect.

' The apparatus employed for this purpose includes a tank adapted toreceive thecolor solution and a valve connected to the tank forcontrolling the mixture. A water inlet pipe communicates with the valveso that when the valve is open the water will unite with the colorsolution at the junction of the The valve thus governs the colorsolution drawn from the tank and also the water inlet for diluting thecolor fluid. When the valve is open the water passing through the pipewill draw the color solution by-tlie suction created at the mouth of thevalve -and the color solution entering at'this 'poi'nt'will thenmix'with the Water to "give the required degree of saturrftion to thecolor. Heretofore clay or other ryfillt 1e colorsolutio'n in order toavoid the mottled effect. The ditliculty with this proeess has been thatthe fillers are sometimes obiectionable to'the use of the paper, andthat the process is too complicated, necessitating the employment ofexpensive machinery. An-

other great drawback of this process is that a large percentage of thecoloring matter is absorbed by the filler, resulting in a weaker, lessperfect, dyeing.

The novel features of the invention are more fully. described in thefollowing specification and claims and illustrated in the accompanyingdrawing in which:

Figure 1 represents a front elevation of an apparatus employed incarrying out this in'veption.

Fig. 2 1s a side elevation partly insection showing the valve open. Fig.3 is a detail. view showing the valve closed.

In this drawing is shown an apparatus provided with a tank a for holdinga suflicient quantity of color dissolved in water. This tank is equippedwith a drain pipe 6 Specification of Letters Patent.

leading from the bottom of the tank to a valve 0. The valve is mountedto actuate in a casing (Z, and it is provided with inlet port e andoutlet port I. The valve 0 carries a short section of a tube 9 whichcommunicates when the valve is open as indicated in Fig. 2, with thelower end of the drain pipe I), while its lower end projects into theoutlet port 7 of the valve. This short tube however could be omitted andthe opening formed in the valve to register with the end of the drainpipe. A pipe having a water inlet h and a color,outlet 'i is secured tothe valve casing and communicates with the valve. A handle or lever j isfixed to the valve 0 for the purpose of operating the valve. The colortank-a is secured to the apparatus by means of bands is. The water inletpipe h can'be connected to a reservoir or other water supply while thecolor outlet pipe 11 leads into the paper pulp. The bottom of the tankis sloped or inclined toward the drain pipe so that no sediment fwillremain in the tank, and. is preferably covered with a screen.

It will be understood that the invention is by injecting a predeterminedvolume of water before the mixture flows into a paper pulp. By thismethod the paper can tinted toa uniform degree and the mottled effect isobviated. It also enables'the use of strong solutions of colors forcoloring any paper where the mottled efi'ect is objectionable.

As shown in the drawing the water pipe is of larger diameter than thecolor'drain pipe so as to gage the proper proportionsof the mixture. Theend of the drain pipe terminates at the lower port of the valve so thatthe color solutionwill completely mix by the sucking action of thedescending Water created at the outlet of the pipe.

The tank a can be graduated as shown at m and in. this way it can beused to indicate the exact proportion of the color and the amount ofwater required to dilute the color.

-I claim:

1. An apparatus for mixing color solutions comprising a tank. adapted tocontain a color solution, means for gaging the solution, a drain pipeconnected to the tank, a.

water inlet pipe, a valve connection between the drain pipe and theWater iii'letfor caik trolling'the Solution and the'water;

2. An apgaratus for. mixing color 56111 tio i's comprising a. graduatedtank arl'lpted' to measure and contain a 00161 solution, a drain pipeconnected to the tank, a, water inlet p1pe,'said drain pipe being ofsmaller" diameter to Proportion the quantity of the 10 solution flowingfrom 'the'tank, a;va'lve coil nection between the drain pipe and theWater inletfo'w controlling the'seii'itiefi and thew'ater."
